Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX1304 is determined by strict equivalence across the following parameters: resistance value (1.3 MOhms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (AEC-Q200, ROHS3). All identified substitutes maintain these electrical and mechanical specifications, ensuring functional interchangeability in automotive and industrial applications.

Parameter Comparison

Engineering Selection Recommendations

CRCW06031M30FKEA (Vishay Dale) is the primary direct substitute, maintaining full AEC-Q200 automotive qualification and active product status with substantial inventory availability (54,270 pcs). This part is recommended for applications requiring uninterrupted automotive compliance.

AC0603FR-071M3L (YAGEO) serves as a secondary substitute with active status and AEC-Q200 qualification, offering moisture-resistant thick film construction. Inventory levels (11,220 pcs) support production requirements.

RC0603FR-071M3L (YAGEO) is functionally equivalent in electrical and mechanical specifications but lacks explicit AEC-Q200 automotive rating. This part is suitable for non-automotive applications or where automotive qualification is not mandated. Inventory availability is limited (5,200 pcs).

Frequently Asked Questions (FAQ)

Q: Can CRCW06031M30FKEA directly replace MCR03EZPFX1304 in automotive applications? A: Yes. CRCW06031M30FKEA maintains identical electrical parameters (1.3 MOhms ±1%, 0.1W), package type (0603), temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. Direct substitution is valid.

Q: What is the difference between AC0603FR-071M3L and RC0603FR-071M3L? A: Both are YAGEO 1.3 MOhms ±1% 0.1W 0603 resistors with identical electrical specifications. AC0603FR-071M3L carries AEC-Q200 automotive rating and moisture-resistant features. RC0603FR-071M3L lacks explicit AEC-Q200 designation. Selection depends on application requirements.

Q: Are all substitutes available in the same packaging format? A: All substitutes are supplied in Tape & Reel (TR) format, matching standard production packaging. Physical dimensions vary slightly within tolerance: MCR03EZPFX1304 and AC0603FR-071M3L measure 0.063" L x 0.031" W, while CRCW06031M30FKEA measures 0.061" L x 0.033" W. Both are within 0603 package specification.

Q: Which substitute has the best inventory availability? A: CRCW06031M30FKEA offers the highest inventory (54,270 pcs), followed by AC0603FR-071M3L (11,220 pcs) and RC0603FR-071M3L (5,200 pcs).

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed substitutes meet ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, matching the original MCR03EZPFX1304 specifications.
